I want to make the Skyp Rib Socks but I think their size small will be too small for me so I want to increase the number of stitches. But I'm not sure the number of stitches needed for the pattern. The Skyp pattern is as such:
Skyp stitch – Slip 1 stitch purlwise with yarn in
back, knit 1 stitch, yarn over, pass slipped stitch
over the last two stitches (k1 and yo).

It's used in the leg pattern like this:
R1 ‐ *K2, p1, skyp, p1* rep. to end of round.
R2 ‐ *K2, p1* rep. to end of round
